摩擦腐蚀是一种系统性的磨损和腐蚀，广泛应用于人工髋关节和膝关节、食品、制药、运输和核工业。一台能够在开放式设施中拥有所有必要的补充分析方法的环境中进行摩擦腐蚀测量的灵敏摩擦试验仪，将使这支杰出的研究团队能够检测到这些机械辅助的界面腐蚀过程。该仪器提供了有关摩擦和磨损类型的详细信息。当与恒电位仪配合使用时，可以同时测量电化学信号，提供有关表面氧化物破坏和腐蚀的信息以及摩擦系数。定制的电池将针对不同的研究项目进行优化，具有独特的要求(例如，氧气含量、温度、痕量金属分析的无污染)。为了进行某些类型的摩擦学研究，例如研究富含蛋白质的环境中的腐蚀机制，包括摩擦、先进的骨科植入材料的磨损和摩擦，以及核动力环境和核废料容器的机械辅助界面腐蚀过程，申请人需要使用先进和灵敏的摩擦轰炸机。需要6mN或更高的力分辨率，才能获得由这些界面过程引起的细微差异的准确信息。 跨学科(工程、医学和科学)团队和不同的申请者已经在基础、医学和工业研究活动方面拥有出色的记录，而一台先进的摩擦轰炸机的加入将使加拿大腐蚀、摩擦学和表面分析研究人员的进一步进步和合作成为可能。收购WESTERN公司的一台敏感的摩擦轰炸机将提高加拿大在摩擦腐蚀方面的研究声誉，该设备将在加拿大国内外的学术和工业用户中广泛使用。 为了最大限度地方便使用，摩擦试验机将设在开放式、低振动的设施中，毗邻补充表面准备和表面表征设备，拥有活跃的研究人员和科学家，能够为HQP用户提供支持并维护设备。团队、工具、培训策略和设施经过精心挑选，以促进HQP的培训和未来高技能的雇用，包括那些来自代表性不足群体的HQP。

Tribocorrosion, involving both wear and corrosion in a systematic manner, occurs in a wide range of applications, including artificial hip and knee joints, food, pharmaceutical, transport and nuclear industries. A sensitive tribometer with the ability to conduct tribocorrosion measurements, in an environment with all necessary complementary analytical methods in an open-user facility, would allow this exceptional research team to detect these mechanically assisted interfacial corrosion processes. This instrument provides detailed information on the type of friction and wear. When coupled with a potentiostat, electrochemical signals can simultaneously be measured, providing information on disruption of the surface oxide and corrosion in conjunction with the coefficient of friction. Customized cells will be optimized for different research projects with unique requirements (e.g., oxygen content, temperature, absence of contamination for trace metal analysis). In order to perform certain types of tribological research such as the investigation of corrosion mechanisms in protein-rich environments involving friction, the wear and friction of advanced orthopaedic implant materials, and mechanically assisted interfacial corrosion processes for nuclear power environments and nuclear waste containers, the applicants require the use of an advanced and sensitive tribometer. A force resolution of 6 mN or better is needed for accurate information on subtle differences induced by these interfacial processes. The team of interdisciplinary (engineering, medicine, and science) and diverse applicants already have exceptional records of fundamental, medical, and industrial research activities, and the addition of an advanced tribometer will permit further advancement and collaboration of corrosion, tribology, and surface analysis researchers within Canada. The acquisition of a sensitive tribometer to Western will boost Canada's research reputation in tribocorrosion, and the device will be widely available to both academic and industrial users within Canada and internationally. To maximize access, the tribometer will be located in an open-user, low-vibration facility adjacent to complementary surface preparation and surface characterization equipment with active research staff scientists able to support HQP users and maintain the equipment. The team, instrument, training strategy, and facility have been carefully selected to facilitate the training and future, highly skilled, employment of HQP, including those from underrepresented groups.
